Inertia (Pendulum album)

Inertia is the fourth studio album by Australian electronic music band Pendulum. It was announced in May 2025, and released on 22 August 2025, making it the band's first full-length album in over 15 years.^[1] The album includes all tracks from their previous 2 EPs; Elemental released in 2021, and Anima released in 2023, as well as new songs.^[2] Excluding works from the previous EPs, the album was preceeded by the singles Napalm (with Joey Valence & Brae),^[3] Save The Cat,^[4] Cannibal (with Wargasm),^[5] and Guiding Lights (with Awolnation).^[6]

When discussing the album, Rob Swire said that he was "basically testing how far we could push Pendulum. Seeing what we could get away with."^[7] The album has been described as a "raw statement of evolution" from the band, and includes collaborations with various artists both within and outside of electronic music.^[8]

To support the album, Pendulum announced a UK tour in November 2025,^[9] which was later expanded to include dates across Europe and Australia.^[10]

Inertia consists of all of the tracks from Pendulum's two previous EPs, Elemental (2021) and Anima (2023), alongside a number of new tracks. The first track from the album to be unveiled was the (at the time) non-album single "Napalm", which debuted in early 2024 as the intro for the band's UK tour. The track continued to be played across Europe at festivals and was formally released in August 2024 to coincide with the band's appearance at Reading & Leeds festivals. Speaking on the track, Rob Swire noted that the band was "only doing singles", and that he hoped to have a more substantial release in the following year. The track's sound was part of a trend by the band to lean into heavier sounds despite the more recent resurgence of the drum & bass genre from which the band had originally come from.^[11] Swire also noted that the album was the sound of Pendulum finding its sound again, comparing it (and the band) to The Prodigy, who had managed to break away from traditional genre conventions and find a sound that was uniquely their own.^[12]

Discussing the album's first single, "Save the Cat", Swire noted that the track was written during a breakup and "a period of self-questioning and frustration".^[12]
